Keyboard for mobile communication terminal {KEY BOARD OF MOBILE PHONE}

The present invention relates to a keyboard for a mobile communication terminal, and more particularly, a mobile communication terminal which can conveniently and quickly input characters by placing all keyboards such as Korean and English on the keyboard while significantly reducing the volume of the keyboard. It is about a keyboard.

As is well known, a keyboard is a device for inputting data into a computer, and the most common of these input devices is a keyboard, which has a large number of buttons on an elongated board, and each button has English letters, Korean characters, and numbers. It is written. Each button is called a key in English, and a collection of these keys on a board is called a keyboard.

The keyboard is used when we want to enter the letter we want. For example, if you want to enter the letter 'A' on your computer, select the key with the letter 'A' on your keyboard and press it lightly. The order of keyboard layout on the keyboard is arranged in the most suitable state through advanced research such as 2 beol or 3 beol type in Hangul. In English, the keyboard layout we use the most is called QWERTY. There is an array of function keys from F1 to F12 on the top line, numbers on the next line, and an alphabetic array on the third line, which shows Q, W, E, R, T, and Y in that order. It is named.

Originally, when IBM made AT class PCs, it called 101 keyboards. The 101 keyboard was the standard for PC keyboards until Windows 95, but since Windows 95, 104 keyboards have become the norm by adding two keys instead of pressing the start button with a mouse and a key corresponding to the right mouse button.

Of course, this is the case in the United States, and in Korea, 106 keys are used, with one additional key to convert to Hanja and one more Korean and English conversion key. It looks complicated because of the large number of keys, but it's not as complicated as you think there are uses and rules for each of the hundred or more keys on the keyboard.

First of all, the shift key of 'shift key' means 'change', and the PC is set to show lowercase letters by default when you first turn on the power, and always lowercase letters. Pressing will cause a capital letter to be entered. In the case of Hangul, you can use the shift key when you want to play the Bokja consonants, such as Ssangbi-eup and Ssang-ji.

Also, the number keys located on the second line of the keyboard have various symbols such as exclamation point and dollar sign, and when you want to input them, you must press the shift key together. After all, the shift key exists to prevent the number of keys from being much larger than it is now by allocating one key to every letter. If you look closely, you'll notice that the shift key isn't just on the left, but underneath the enter key.

However, such a conventional keyboard has a problem in that its size is large and cannot be used in a mobile communication terminal.

Therefore, in a mobile communication terminal such as a conventional cellular phone, it is necessary to input Korean, English, and function keys by applying a numeric key, and thus there is a problem that the input method is complicated and inconvenient and cannot be input quickly.

Therefore, the present invention is to solve the above-mentioned problems in the related art, a mobile communication that can conveniently and quickly input characters by placing all keyboards such as Korean and English on the keyboard while reducing the keyboard volume significantly. Its purpose is to provide a keyboard for a terminal.

Another object of the present invention is to provide a keyboard for a mobile communication terminal that allows the user to easily recognize the keyboard layout by arranging according to the shapes of the consonants and vowels of the keyboard.

Another object of the present invention is to provide a keyboard for a mobile communication terminal that can easily complete a sentence without the need of a letter combination by allowing one keyboard to write all the double consonants, double vowels, etc. on the keyboard.

Another object of the present invention is to provide a keyboard for a mobile communication terminal that can be used with a mouse function as a keyboard by wireless or wired connection of a desktop computer or a notebook computer.
